Everything You Should Know About Your Electric Skateboard Battery

Looking After The Battery In Your Electric Skateboard

Batteries used in electric skateboards are usually rechargeable Li-ion batteries. The advantages of Li-ion batteries over old lead-acid batteries are huge. First of all, the weight of the batteries is much lighter over lead-acid ones. For example, lead-acid batteries with the same capacity as Li-ion products weigh around 35lbs while the Li-ion one’s weigh about 11lbs. The lifetime of a Li-ion battery varies, but they have an average life of around 1000 cycles. If you put that in perspective, 1000 charges is a lot.

Considering you’re not going to charge your battery every day, the lifetime expected is around five years. Choosing the right accessories and parts for your electric skateboard is essential if you want to avoid potential problems. For that reason, we will compare these two types and try to provide you with enough information to help you make a right decision.

Differences Between Li-ion & Lead-Acid Batteries

Li-ion batteries are lighter and smaller. On top of that, it is portable due to its light weight and has a lifetime 5-10 times longer than that of the lead-acid battery, and it’s also five times more efficient.

Li-ion batteries last much longer. Expected charging cycles for Li-ion batteries is around 1000, and the expected charging cycles for lead-acid batteries is 50-200 times. Each Lithium cell carries a higher voltage with greater consistency, and there is no loss of acidic steam.

The low internal resistance is also an advantage of Li-ion batteries. They can provide much more power when power is needed, such as accelerating and climbing steep hills. The working voltage of a Li-ion battery is 3.7V. The operation voltage of a lead-acid battery is 2V. The temperature resistance is also quite significant. Li-ion batteries can work with 90% efficiency at -40C. Lead-acid batteries, however, have only about 60% efficiency at 0C. Therefore, Li-ion have much more temperature tolerance.

Charging and Capacity

A lithium battery can discharge up to 25A while lead-acid discharge only around 15A. Most electric skateboards nowadays need at least 30A to function flawlessly. However, only around 8A is enough to run electric skateboards on a flat surface. Self-discharge is much lower with Li-ion batteries as well. Lithium batteries have around 6-8 percent of self-discharge per month, while lead-acid can have up to 15 percent of self-discharge. That means after being recharged; Li-ion battery can be stored longer than lead-acid ones.

Environment preserving is a major factor. Li-ion batteries are much more nature-friendly. They are free of leakage, pollution, and harmful metals (such as lead and mercury). There is no contamination during production. The lead battery, however, is a different story.

The proper charger is paramount. Overcharging cells will damage them regardless of the quality of the battery; it also can be quite dangerous. The main advantage of Li-ion charges is that they cut out the power as soon as the battery reaches 100%. Lead-acid charges, on the other hand, don’t cut the power out. You can see the potential danger of leaving the lead battery charging overnight and not cutting the power out. When it comes to batteries, if you over discharge them, or discharge them too rapidly you will drastically reduce the life of the battery.

With more battery capacity comes more range. Anyt product which is over 20A can cover up to 19 miles. In 2016 few companies started manufacturing cells with the ability to run over 19 miles with one charge, unlike their predecessors which offer 15 miles of range and cost almost double the price.


The batteries determine your range. Modern Li-ion batteries cover up to 20 miles of range depending on your weight, the pressure on the board, and the terrain. Charging is reduced to 2-5 hours in oppose to old lead-acid batteries which need up to 12h to recharge fully.
